* Ansible: move to Ansible 3.4.0 which uses ansible-base 2.10.10
* Docs: add a note about ansible upgrade post 2.9.x
* CI: ensure ansible is removed before ansible 3.x is installed to avoid pip failures
* Ansible: use newer ansible-lint
* Fix ansible-lint 5.0.11 found issues
* syntax issues
* risky-file-permissions
* var-naming
* role-name
* molecule tests
* Mitogen: use 0.3.0rc1 which adds support for ansible 2.10+
* Pin ansible-base to 2.10.11 to get package fix on RHEL8
* rename ansible groups to use _ instead of -
k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating
Note: kube-node,k8s-cluster groups in upgrade CI
need clean-up after v2.16 is tagged
* ensure old groups are mapped to the new ones
This replaces kube-master with kube_control_plane because of [1]:
The Kubernetes project is moving away from wording that is
considered offensive. A new working group WG Naming was created
to track this work, and the word "master" was declared as offensive.
A proposal was formalized for replacing the word "master" with
"control plane". This means it should be removed from source code,
documentation, and user-facing configuration from Kubernetes and
its sub-projects.
NOTE: The reason why this changes it to kube_control_plane not
kube-control-plane is for valid group names on ansible.

Just after creating a namespace, the corresponding token could not be
created and sometimes the pod creation might be failed.
This adds check of the token in the new namespace to make this test
case stable.
* Use K8s 1.15
* Use Kubernetes 1.15 and use kubeadm.k8s.io/v1beta2 for
InitConfiguration.
* bump to v1.15.0
* Remove k8s 1.13 checksums.
* Update README kubernetes version 1.15.0.
* Update metrics server 0.3.3 for k8s 1.15
* Remove less than k8s 1.14 related code
* Use kubeadm with --upload-certs instead of --experimental-upload-certs due to depricate
* Update dnsautoscaler 1.6.0
* Skip certificateKey if it's not defined
* Add kubeadm-conftolplane.v2beta2 for k8s 1.15 or later
* Support kubeadm control plane for k8s 1.15
* Update sonobuoy version 0.15.0 for k8s 1.15
* Disable kube_api_anonymous_auth by default to secure the setup
* Disable metrics-server in addons. Health endpoint is slow and unstable
* Fix anonymous-auth missing in configuration
* Cleanup a bit
* Fix kube anon auth
Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.
* Lint everything in the repository with yamllint
* yamllint fixes: syntax fixes only
* yamllint fixes: move comments to play names
* yamllint fixes: indent comments in .gitlab-ci.yml file
